Vehicle body reinforcing structure for coping with small overlap collision

Abstract

A vehicle body reinforcing structure for coping with a small overlap collision may include front side members which may be extended in a longitudinal direction of a vehicle and disposed at left and right sides in a width direction of the vehicle, a crash box which is installed to a front end of the front side member in the longitudinal direction of the vehicle and absorbs and reduces impact when receiving the impact to be deformed, a bumper beam which is disposed in front of the crash box in the longitudinal direction of the vehicle, coupled to the crash box, and extended in the width direction of the vehicle, and a reinforcing member which is coupled to both the crash box and the front side member, and protrudes outside of the bumper beam in the width direction of the vehicle to transfer an impact energy to the front side member.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]The present application claims priority to and the benefit of Korean Patent Application No. 10-2014-0062550 filed on May 23, 2014, the entire contents of which is incorporated herein for all purposes by this reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a vehicle body reinforcing structure for coping with a small overlap collision, and more particularly, to a vehicle body reinforcing structure for coping with a small overlap collision which makes it possible to enhance small overlap collision response performance by increasing a collision area and width against a small overlap barrier when a front small overlap collision occurs.[0004]2. Description of Related Art[0005]In general, a front vehicle body of a vehicle is a frame structure which is positioned at a front side in the longitudinal direction of a vehicle while forming an engine compartment, and includes a front end module ...

AI Technical Summary

Benefits of technology

The present invention provides a vehicle body reinforcing structure for coping with small overlap collisions that can enhance front small overlap collision response performance of a vehicle in such a way to increase a collision area and a collision width against a small overlap barrier in the case where the vehicle collides with a small overlap collision barrier at its outer edge portion in the width direction of the vehicle while efficiently transferring impact energy toward the front side member, so that the front side member is properly deformed, thus efficiently absorbing and alleviating such impact, and distributing the impact to other portions of the vehicle body. The front side members, crash box, bumper beam, and reinforcing member are designed to efficiently absorb and alleviate impact energy during a small overlap collision, protecting the vehicle and its occupants from damage and breakdown.

Problems solved by technology

Due to this, when the front side member does not perform an impact absorption function well, the absorption of impact energy and the transfer of the impact energy to another portion are not smoothly performed, such that excessive damage or breakdown may partially occur at the vehicle body, and the impact energy is excessively transferred to the passenger compartment, thereby threatening passenger's safety.
